Introduction
A process of making three dimensional solid objects from a
digital file
Make use of 3D printing to make
conceptual models, functional prototyping, manufacturing tools ,
production tools, mold manufacturing and end-use parts
Several ways to do 3D printing:
Selective laser sintering, fused deposition modeling,
stereolithography
Project Information Search Strategies
1) Subject Directory
offers a collection of links to Internet resources submitted by site creators or
evaluators and organized into subject categories
useful conducting general research or want to find resources recommended by
experts and evaluators.
2) Search Engine
a searchable database of Internet files collected by a computer program
looking for a particular web site, have a specific research question, or are looking
for the most current information
** Use Specific Words - 3D Printing
** Use Research Operators - “3D Printing”
Library Resources
Mind Map
Online Survey
Purposes of the survey:
- To understand how much the general public
know about the 3D printing technology
- To understand how people feel about future
development of 3D printing technology

Do you know some places using 3D printing now?
Yes
No
We can see that most of the interviewees have not tried to
use 3D printer. And this can show that 3D printing is still
not quite common to general public nowadays.

Future Development
More research and development on 3D printing Technology
e.g. Find more new materials
Refine the printing skill
e.g. Print more complicated objects
Find some ways to reduce cost and enhance durability
Make it more environmentally friendly and energy saving
Suggestion: Rocket parts
Conclusion

technology, but only limited to basic level
Minority of people have used 3D printing before
Majority of people have high expectation on its
future development and bring great contribution
to the future world
